PREVENTIVE MAINTENANCE
This recommendation is intended for maximum efficiency of RO water production by your system.
1) Filter maintenance
a) It is OK to put filters on the shelf for several years.
b)
To keep the sealed, non-opened filter, we recommended to put it into some air
-tight container,
preventing it from absorbing the air. This prolongs the shelf life of carbon filter (particularly, if you
order the replacement filter for more than one years usage) and avoids any possible odor from the
air.
2) Membrane maintenance
a) The dry packed membrane usually has a two-year shelf life. To prolong the shelf life, we
recommended keeping non-opened dry membrane in refrigerator
.
b) Once being used, we recommend you run the RO system every day, at least 2 minutes (about 1
gallon or 4 liters drinking water). This helps to maintain the membrane performance.
c) If you do not use the RO system for long periods, drain the storage tank before using. Fill the tank
and drain it twice. Your RO system is then ready to use.
3) Filter and membrane change procedures:
a) Shut off the water supply.
b)
Turn off the tank ball valve by turning 90 degree.
c)
Open RO faucet to continuous flow position.
d) Lift the filter housing up 1" and slid on the housing wench. Use one hand to hold the system and the
other hand to turn the wrench counter-clockwise to open the housing.
e) After opening the housing, remove the used filter and put the new filter into the housing. Make sure
the O-ring is in place and turn the housing clockwise to close.
f) Repeat previous step on the subsequent filter changes..
g) Turn on the water supply and make sure there are no leaks.
h) Let the water drip from faucet for about 10 minutes. If the water flow is less than 1 cup (8 oz. or
240 ml) per minute, it may be an indication to change the membrane.
i) Membrane change procedures:
• Unscrew the cap of the membrane housing.
• Slid out the used membrane and discard.
• Insert the new membrane with 2 o-rings into housing first, the black brine seal around membrane last.
Be sure it is fully seated into bottom end
• Screw cap back on to the membrane housing, make sure o-ring is still in place.
• It may take 10-20 minutes for new membrane to run to normal flow.
If the water flow is OK, then turn on the tank ball valve. After 1 minute, turn off the RO faucet and
complete the filter change procedures.
Note: If it is too tight to open the housing you may try to unplug the fitting between red tubing
and the systems in order to reduce the air and water pressure inside the housing
